Question

我为scrapy写了一个自定义命令：

from pyes import *
from eScraperInterface import settings
from django.core.management import setup_environ
setup_environ(settings) 
from eScraperInterfaceApp.models import scrapedData
from eScraperInterfaceApp.eScraper_utils import eScraperUtils 
#------------------------------------------------------------------------------ 

class indexData():

    def __init__(self):
        self.utilsOBJ = eScraperUtils()
        conn = ES('127.0.0.1:9200')
        conn.create_index("scraped_data")

    def run(self):
        for i in scrapedData.objects.filter():
            data = {'productTitle':i.productTitle,'productSite':i.productSite,
                    'productURL':i.productURL,'productDesc':i.productDesc,
                    'productCategory':i.productCategory,'productSubCategory':i.productSubCategory,
                    'productMRP':i.productMRP,'productPrice':i.productPrice,'hasVariants':i.hasVariants,
                    'availability':i.availability,'currency':i.currency,'image_paths':i.image_paths}

            a = self.utilsOBJ.create_Index(data)
            print a

当我尝试使用scrapy shell命令时出现此错误：

    from django.db import utils
ImportError: cannot import name utils

Answer 1

你在系统上安装了python-mysqldb吗？ sudo apt-get install python-mysqldb 或者pip install mysqldb

来自django.db import utils ImportError：无法导入名称utils错误
